Answer:
There would be 12 gallons left
Step-by-step explanation:
If there was 76 of the 2 quarter pitchers that would make 152 Qt and 152 Qt equals 38 gallons so 50 - 38 = 12
Answer:
$51.1
Step-by-step explanation:
If Joe spent 15/22 of his pocket money in a story book which costs $75, he had $51.1 at first.
15/22 of 75 = 51.1363636364 or 51.1
(2x^3+x+3)/(x+1)=2x^2-2x+3
So here you're using system of equations. You can solve systems by graphing, elimination, or substitution. Ill use substitution. First lets solve for x. take the second equation and add y to both sides to get x by itself:
x - y = 75
x = y + 75 now plug y+75 in for x in the first equation
x + y = 743
(y +75) +y = 743 solve for y
2y +75 = 743 subtract 75
2y = 668 divide both sides by 2
y = 334
now plug this into any of the 2 equations to solve for x i chose the second one
x - y = 75
x - 334 = 75 add 334 to both sides
x = 409
This means x, sold before the tournament is 409 and y, sold at the door is 334. That means the assistant is wrong and accidentally flipped the two answers
